Mary I Irish Penny

This Irish penny from Mary I's reign was one of the first base metal coins issued for Ireland by a female monarch, marking a shift from earlier silver issues. Struck at the Tower Mint in London, it used simple dies that often resulted in off-center strikes.

The obverse features a crowned bust of Mary facing right, while the reverse shows a crowned harp, Ireland's traditional symbol. These details reflect the Tudor administration's effort to unify currency, though the coins were made from low-quality alloys that corroded quickly.

Exact mintage figures are unknown; records from that era are scarce, possibly destroyed in later conflicts. What we do have are survivors in various states, from worn circulation pieces to rare proofs.

Some numismatists note the irony in these coins' scarcity today. After all, base metal was meant to be common, not collectible.
